Title: Apparatus and method for molding container
Inventor: OKUSHITA MASATAKA
IPC: B31B50/00
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To form a protruding strip of a predetermined size while reducing a force to be applied to a container by gradually forming the strip along a circumferential direction of the container. SOLUTION: A groove having a substantially circular arc-like section complementary with an outer periphery 26a of a flange 26 is formed at a center of an outer periphery of one stamping roller, and a groove 46b having a substantially circular arc-like section complementary with an outer periphery 37a of a flange 27 is formed at a center of an outer periphery of the other stamping roller 46B. When the one roller is brought into contact with a sidewall 2a so that the sidewall 2a is pressed into an inside, the sidewall 2a is sandwiched between the groove and the periphery 26a of the flange 26, and a nature is given to the sidewall 2a to generate a peter line 2d as a protruding stripe.  At this time, since a cup body 2 and the flange 26 are rotated, a contact position of the roller with the sidewall 2a of the body 2 is circumferentially sequentially changed, and the line 2a is gradually formed circumferentially of the body 2.

Title: Display device
Inventor: TOSHIYASU MASAYUKI
IPC: H01J29/86
Filed: 1984-05-28
Abstract: PURPOSE:To shield the external unnecessary magnetic field produced from a deflecting yoke with a simple means by covering almost all the CRT funnel portion and the deflecting yoke with non-magnetic and high conductivity metallic material. CONSTITUTION:Almost all the area of a funnel portion 1a of a CRT1 and whole of a deflecting yoke 2 are covered with a shield box 6 made of a non-magnetic and high conductivity metallic material such as aluminum. By this construction the external unnecessary magnetic field produced by the deflecting yoke 2 interlinks the shield box 6, in particular its high frequency horizontal component, produces eddy current in the shield box 6, and the magnetic field is cancelled, and thus the horizontal component of the external unnecessary magnetic field is prevented from leaking outside. The higher the frequency is, the more quantity of eddy current flow. The vertical component of the frequency of 50-60Hz is given little effect.

Title: Rectifying circuit
Inventor: YADA TAKAAKI
IPC: H02M7/21
Filed: 1985-05-21
Abstract: PURPOSE:To rectify a low frequency AC signal precisely at an extremely high speed with relatively simple constitution by providing a hold output means which holds and outputs the peak value of an input AC signal. CONSTITUTION:An amplifier B for phase conversion receives the input AC signal V0 and generates a phase-converted AC signal V1 which is 90 deg. out of phase with the input signal and a zero-cross comparator C detects the zero-cross timing of the phase-converted AC signal V1 from the positive side to the negative side and generates its detection signal V2. Then, a monostable multivibrator D sends out a peak value hold command signal V5 for holding the value of the current input AC signal V0 in an output holding amplifier A in response to the detection signal V2. Consequently, the output holding amplifier A holds and outputs the positive peak value of the input AC signal V0 successively.

Title: Image processor
Inventor: KONO HIROSHI
IPC: H04N9/09
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To effectively control moires by using a spatial filter and to efficiently enhance edges by the use of the spatial filter. SOLUTION: When a spatial filter processing for moire elimination is performed, the MTF of the entire spatial frequencies capable of being included by an image is defined as 1.0 or smaller, and the MTF of a spatial frequency in which moires are difficult to be generated is defined as a minimum value in the characteristic of a spatial filter processing part 27 of an image processor 14. Thus, the processor 14 can prevent deterioration of an image after the spatial filter processing. Also, when spatial filter processing for edge enhancement is performed, the MTF of an erroneous decision spatial frequency band in which edge extraction is easily mistaken is defined as flat and the MTF of a spatial frequency less than the lower limit value of the wrong decision frequency band also exceeds 1.0. Thus, the image processor can prevent deterioration of an image after spatial filter processing.

Title: Collapsible barrel type camera provided with barrier mechanism
Inventor: HARAGUCHI KEISUKE
IPC: G03B17/04
Filed: 1993-05-12
Abstract: PURPOSE:To automatically open and close a barrier by executing it by utilizing a moving action between the photographing feasible position and the housing position of a photographing lens frame. CONSTITUTION:An opening and closing pin 36 is positioned at the projecting end of a radial direction by the spring force of the spring arm 34b of an opening and closing spring 34 in,Q a state where external force is not added on it. At this time, a barrier plate part 31a is retreated from an optical path. That means, the barrier 31 is opened. On the other hand, when the pin 36 is pressed inside in the radial direction through an interlocking lever 38, the part 31 is turned through an actuation arm 34a and the barrier plate part 31a thereof is positioned on the optical path as the result that a driving arm 34c is pressed. That means, the front side of a front lens group is closed. Then, the lever 38 is pressed by a closing projection 40 projectingly formed on the inside surface of a cam ring 14 when the ring 14 is turned within an opening and closing section. Thus, when the ring 14 is turned to one turning end by a zoom motor, the barrier 31 is automatically closed.

Title: Method and device for preparing binder-free hot briquet
Inventor: HAINRITSUHI RERERUMAIYAA
IPC: C22B1/24
Filed: 1983-06-21
Abstract: The invention relates to a process and an apparatus for preparing binder-free hot-briquets for smelting purposes from ferrous pyrophorous, finely divided solids, such as dry steelmaking-filter dust or slightly granular sponge iron from direct-reduction plants. Before the briquetting stage, oxidizing gas is blown at a temperature of more than 200 DEG  C. through the finely divided dry solid containing more than 4% by weight of metallic resin. The flow rate of this gas is controlled in such a way that oxidation of some of the metallic iron raises the temperature of the finely divided solid to 450 DEG  C. to 650 DEG  C. This is followed by hot-briquetting.

Title: Die set for powder molding press
Inventor: SUGIMOTO AOI
IPC: B22F3/02
Filed: 1986-05-12
Abstract: PURPOSE:To simplify construction and to prevent failure by receiving lower punches during compression by a base plate and driving cylinder actuators connected to the respective lower punches to remove the molding from dies after the compression and to reset the lower punches to the home positions. CONSTITUTION:A powder material D is supplied into a cavity 3 and an upper punch 11 descends and is inserted into the cavity. A die 1 descends as well together with the plate 2 and yoke plate 9 to start the compression. The lower punch 6 descends as well together with a holder 10 at the same instant. The holder 10 is received by the base plate 7 to complete the compression when the die 1 and the upper punch 11 descend down to the prescribed position. The die 1, driven by a lower ram B, continues to descend even after the completion of the compression so that the top surface of the die 1 is brought lower than the top surface of the upper punch 6. The molding is thus removed from the die. The cylinder actuators 20 are thereafter driven and the upper punch 5 is lifted up to the position where an adjusting ring 27 contacts the surface 28. The molding is thereby removed from the upper punch 6.
